I've finished all the Jack Reacher books as well as the Harry Bosch series. I really enjoyed the Millennium Trilogy and started reading a number of Scandinavian police procedurals. Kjell Eriksson's books were pretty good too. One of the best series I have ever read was the Martin Beck series by the team of Maj Sjowall and Per Wahloo. I just started Iris Johansen's 'Close Your Eyes'.
Any suggestions on another series?
